When I took my Nitrox class and again when I took a VIP class, the issue of partial pressure blending came up and there was a lot of emphasis put on making sure that any 02 clean tank was only filled with "super clean" air. I think it was grade "E" but I don't have my notes.
Can someone point me to the specs for the different air grades or tell me what the contamination difference is between "super clean" air and "normal" dive air?
